PATENT COMBINED ELECTRICAL WEIGHING-SCA LE AND FLOUR AND BRAN PACKER.

)PECEFIGATION forming part of Letters Application filed October 22, 1884.

To all whom, it may concern.-

Be it known that I, CHARLES W. ROTH, a citizen of the United States, residing at Evansville, in the county of Vanderburg and State of Indiana, have invented certain new and useful Improvements in Combined Electrical Weighing-Scales and Flour and Bran Packers, of which the following; is a specification, ref ereilce being had therein to the accompanying drawings.

This invention relates to improvements in combined electrical scales and flour and bran packers, and has for its objects to weigh, automatically, given quantities of flour, bran, or grain, and pack the same in sacks, barrels, or other receptacles, in order that any number of packages may be filled with uniform quantities automatically.

The objects are attained by the mechanism illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is an elevation taken from one side of the machine. Fig. 2 is an elevation taken from another side of the machine. Fig. 3 is a plan with some of the parts removed and some parts broken away. Fig. 4 is a detached view of the feed-rollers. Fig. 5 is an elevation with some of the parts removed and broken away. Fig. 6 is a detached view showing the scale-beam, a portion of the rod connectingit with the platform, and the electrical connections. Fig. 7 is a detailed enlarged view showing the means for uniting the drive-shaft and the shaft for operating the feed-rollers, and Fig. 8 an enlarged side elevation of the devices for holding and releasing the rod E, whose functions hereinafter appear.

A indicates vertical posts forming a part of the frame of the machine; A, the base or floor; A A, transverse frames which connect the frames Ato one another. B is aframe,which forms the bearings of two fluted feed-rollers, b I), which are provided, respectively, with shafts b 1/, having a spur-and bevel gearing, I), and spur-wheel I), by means of which'ro tary motion is imparted to the fluted feedrollers b b by the bevel-wheel C,which meshes into the bevel-gearing b, and is attached to the vertical shaft 0, which is provided with a long journal, 0, at its upper extremity, having Patent No. 321,387, dated June 30,1885.

(No model.)

a bearing in the bracket 0', attached to the frame B. The long journal 0 permits the shaft 0 to be raised, and thereby throw the bevelwheel 0 out of gear with the bevelgearing If.

The upper part of the frame 13 has a hinge, If, by which the cross-piece B is connected thereto. On one end of said piece B is a setscrew, B, by means of which the cross-piece B may be raised or lowered, and thus regulate the quantity of flour, bran, or other material which is allowed to pass between the two feed-rollers b b. The frame 13 rests upon the top of the feed-box B, and is secured thereto in any suitable manner.

The feed-box B rests on top of the plat form of an iron scale box or frame, D, supported in the same manner as the platform of an ordinary scale, and made of a single casting. This platform is composed of pivoted slats D D, and forms the bottom of the feedboX. These slats when in a horizontal posi tion retain the contents within the feed-box, but when turned on their axes permit the contents to drop through into the packing devices below. Each slat has a shaft or pivot, (1, provided with a crank, (1, each of which cranks engages with a beam or connecting-link, d, whereby all of the slats may be turned upon their axes simultaneously,in the manner hereinafter described.

The slat D has its shaft d made a little longer than the other shafts of the series, and thereby extends beyond the end of thescalebox D, as shown on the right-hand side in Fig. 3, and has an arm, D, attached thereto at a right angle, as shown on the right-hand side in Fig. 3. This arm D has an adjustable weight, D", which holds the slat D, together with the slats D, in a horizontal or closed position until opened by the action of the weight E, which is hung to one of the arms of abell-crank lever, E, the upper end of which bears against a fork in the outer end of the beam (1 whenever the vertical shaft E is released from the holding mechanism at its lower end. This freeing of the shaft E allows the weight D" to turn the arm D on its pivotal point, and thus throw the upper end of said arm against the beam (1 and operate the cranks d, as seen in Fig. 3, and open or separate the slats.

The scale-box D is provided with a series of doors, 1, on its opposite sides, which, when opened, permit the machinery of the scale to be seen and any accumulations therein to be removed therefrom.

The vertical shaft 0 has a bearing, 0, near the bottom, in which it slides freely up and down, and at the lower end a square socket, which fits over a projecting key at the upper end of the shaft F, by means of which rotary motion is imparted to the shaft 0 when the machine is in operation, and the key and sockct are permitted to engage with each other, as

clearly seen in Fig. 7. A forked lever, O, straddles the bottom of the shaft 0, and is for the purpose of raising and lowering the shaft 0, and thereby throwing the bevel-wheel Gin and out of gear with the bevel-gearingd". The outer end of the forked lever G is provided with a rod or cord, 0, having at its lower end a hook, c", which is intended to engage with a nail or button located at any convenientpoint below, whereby the lever 0 maybe held down when it is desired to raise the shaft 0, which is done by pulling the cord 0 in a downward direction.

The vertical shaft or rod E is connected to the bell crank lever E by means of a rod or link, 0, the upper end of which is formed into a loop or hook, e, by means of which it is at taehed to the bell crank lever E. The lower end of the rod 0 is of L shape, and is adapted to enter any one of a series of openings in the top of the shaft E, which has a slot to receive the outer end of a lever, E, having an opening for the passage of the L-shaped portion of the rod 0, whereby the lever 13 and the shaft E are pivoted to each other by the rod 0, when passed through the opening in the end ol'the lever E,and anytwo of the openings in the slotted partof the shaft E, heretofore described. The inner end of thelever E enters a slot in one side of a vertically-sliding box, E, which forms the bearing of a shaft, F. \Vhen the outer end of the lever E is depressed, the box IE is raised; and, on the other hand, when the lever 13 is raised the box IE" will. be lowered, for purposes hereinafter described.

The lower end of the shaft E has a hook, e, which is intended to engage with asliding bolt, N, by means of which the shaft E may be held down when the said shaft E is de- 1)IGSSG(l,SO as to engage with said bolt. This shaft E is depressed by means of the lever G, having one end pivoted to the frame A, and being also pivoted to the shaft E. The outer end of this lever G is formed into ahandle in order that it may be easily grasped and held by the operator or workman. A cord, 9, extends from the lever Gin an upward direction, and is attached to a lever, G, whereby these two levers G and G may be depressed simultaneously.

The lever G extends through an openingin one side of the tube or cylinder H, andhas on its inner end a fork, G, which fits into a groove, 1, in a collar, G. Surrounding the shaft F,and from the bottom of this collar G, extend downwardly three spiral pieces of sheet metal, 9, thelower ends of which are attached. to the hollow shaft (or its equivalent) G", having attached to its lower extremity the trans verse arms I. The spiral pieces 9 pass between three wings, F, attached spirally to the shaft F, (after the manner of a screwpropeller.) As these pieces 9 bear against the wings F,when the lever G is moved up or down the arms I have two motions-viz., an up-anddown motion and a partly rotary motion, by means of which the bran or flour within the cylinder H may be more or less shaken, and thereby be caused to flow more evenly in a downward direction when propelled by the spiral wings F and the auger-shaped disks F, which latter are secured to the lower ex tremity of the shaft F,which,when revolving, causes these disks and wings F to act in the manner of a screw to press the contents of the cylinder H into any receptacle placed below the mouth of the cylinder to receive it-such as barrels or bags. A platform, 1i, attached to frame A of the machine, supports the cylinders H H, as well as the fulcrum of the lever G.

A box or casing, J, attached to frame A, extends from the bottom of the scale-box D in a downward direction, and has attached to it at the bottom an arm, J. This box or case J incloses a vertical rod, j, attached to the bottom of the scale-box D. The rodj has its lower extremity pivoted to thescale-beam J", which is pivoted to the arm J, and extends outwardly through a metal loop. j.

\Vhen the flour or feed box 13 has received the desired quantity of flour or bran,the weight thereof causes the scale-platform to descend and bear upon the rod j, which will then bear upon the inner end of the scale beam and cause the outer end to rise. Therefore if the wires of an eleetro-niagnet and galvanic battery are connected in the circuit, one wire, 7;, to the inner end of the metal scale-beam J, and the other wire, k, to the metal loop j, the circuit will be closed when the beam J is in contact with the loop j, and the armature be attracted and held down upon the pole of the magnet as long as the current of electricity continues to flow.

L indicates a galvanic battery. is L are wires leading therefrom. The wire 7.: extends from one element of the battery L, (either carbon or zinc,) and is then wound spirally around the cores of the electro-magnet- L, then along the top of frame A, then upwardly along the frame A, then through or around said frame A, as shown in dotted lines in Fig. 2, then to the loop j, to which it is electrically connected. The wire 7.: is connected to the other pole of the battery L, and then carried upwardly to the frame A, then in a horizontal direction above said frameuntil it reaches the frame A, then upwardly along frame A, then through or around said frame A to the inner end of the metal scalebeam J, to which it is (electrically) attached. Fig. 2 indicates the course of these wires.

L is an electro-magnet. L its armature, which is attached to the lever L, pivoted to the frame A. The end Z of the lever L engages with a detent or pawl, Z, pivoted to the top of a sliding weight, M. O is a foot-treadle pivoted to the frame A, one end of which ex tends under the weight M,and serves the purpose to raise the weight when the outer end of the treadle is pressed upon by the foot of the operator.

0 is a cushion secured to the base A, and is intended to break the force or jar of the weight M when released from its holding mechanism, consisting of the bolt N, staples an, bell-crank lever Z, pawls Z l and lever The scale beam J is provided with an insulator, j, placed at the top or out-er end, which may be made of any material suitable forthat purpose.

The weight M is suspended by means ofthe lever L and the armature L, which is held down upon the electro-magnet L, and kept in that position until released by the breaking of the circuit of the electric current, (generated by the battery L,) which is done when the scale beam rises and becomes separated from the loop j. Then this occurs, thelever L is allowed to turn uponits pivot, and this releases the pivoted detentor lever Z,which supports the weight M when in its elevated position, as seen in Fig. 1. \Vhen released, the weight M draws the pawl Z in a downward direction and turns the bell-crank lever Z upon its axis, and as this lever Z is connected to the bolt N by staples or links a a the bolt N is drawn in a direction to compress the spring N, and this forces the bolt N back from under the hook e" of the shaft E, allowing the shaft E to fiy up and throw the whole machine out of gear.

1? P are guides for a platform or carriage upon which the packages to be filled may be placed, which platform may be raised and lowered by means of ropes or chains on pulleys t, which are secured to a shaft, T, which has a hand wheel, R, and a pulley, T, provided with a rope or cord, 15, attached to a counterbalance-weight, T. T is a collar attached to the shaft T. A lever, S, having notches s,is pivoted to the frame A,and is provided with a weight, S, hung thereon so as to engage with any one of the notches s, whereby it may be kept in any desired place on the lever S. To the inner end of the lever S is pivoted a vertical shaft, S, enlarged at its upper end and curved to fit the lower part of the collar T, whereby pressure may be given to the collar T by means of the lever S and its adjustable weight S", so that the rotation of the shaft T may be accelerated or retarded at will, according to the position of the weight S, whether placed near or farther from the pivot or fulcrum of said lever S, and by this means regulate the descent of the carriage or platform supporting the vessel while being tilled or packed.

The vertical shaft F is provided with a bevel-wheeLf, which meshes into the bevelwheel f on the shaft F, which has a bearing in the sliding box IE". At the bottom of this box, and pivoted thereto, is the lever E. It will therefore be readily seen that when a downward pressure is made upon thelever G, the shaft IE will be drawn downward, together with the lever E, secured at e to the shaft E, and thus force the sliding box E in an upward direction, and thus throw the bevelwheelsff into gear and cause the rotation of the shaft F.
